2-in-1 Bike Light & Headlamp | 15000 Lumens | 3*XHP70.2 LEDs | 2 Intelligent Cooling Fans | 30000mAh Battery | 10-16 Hour Runtime | USB-C Rechargeable | 90° Adjustable
The Helius H-M4 is a professional 2-in-1 bike light and headlamp engineered for cycling, hiking, and demanding outdoor use. Switch between headlamp mode and bike light mode with the included bike mount — perfect for night riding, camping, and professional work.
Equipped with 3*XHP70.2 LEDs, the H-M4 delivers an incredible 15000 lumens of bright, penetrating light. Whether you are riding on a dark trail, inspecting a job site, or working in low-visibility conditions, the focused beam cuts through the dark for clear visibility. Multiple modes include 3%, 10%, 30%, 60%, 80%, and 100% brightness, plus Turbo and Strobe.
Unlike ordinary high-power headlamps that overheat and throttle down, the H-M4 features 2 intelligent cooling fans that actively dissipate heat. This allows it to maintain stable output for extended periods, making it ideal for long-duration cycling and professional use.
Powered by 6*21700 high-rate batteries (30000mAh), the H-M4 offers an exceptional runtime of 10 to 16 hours. A built-in battery indicator shows green when voltage is above 6.5V and red when below 6.5V (low battery), with automatic shutoff below 5.5V for safety.
